Superposition Coded Modulation Based Faster‐Than‐Nyquist Signaling
Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018 A structure of faster‐than‐Nyquist (FTN) signaling combined with superposition coded modulation (SCM) is considered. The so‐called FTN‐SCM structure is able to achieve the constrained capacity of FTN signaling and only requires a low detection complexity. By deriving a new observation model suitable for FTN‐SCM, we offer the power allocation based on a

Differential Faster-Than-Nyquist Signaling
IEEE Access, 2018 In this paper, we propose a novel differential faster-than-Nyquist (DFTN) signaling concept that allows us to dispense with any channel estimation at the receiver, while benefiting from a rate boost specific to faster-than-Nyquist (FTN) signaling.

Pre-Equalized Interference Cancellation for Faster-Than-Nyquist Signaling
IEEE Access, 2019 An affine projection (AP)-based equalizer (APE) is introduced to eliminate the inter-symbol interference (ISI) for faster-than-Nyquist (FTN) signaling. Based on the APE, a pre-equalized interference cancellation (PIC) algorithm is proposed to eliminate ...
